Subject: [PATCH net-next v2 3/4] rds: Fix endianness annotation for RDS_MPATH_HASH
Date: Wed, 20 Aug 2025 23:25:49 +0530 [thread overview]
Message-ID: <20250820175550.498-4-ujwal.kundur@gmail.com> (raw)
In-Reply-To: <20250820175550.498-1-ujwal.kundur@gmail.com>
jhash_1word accepts host endian inputs while rs_bound_port is a be16
value (sockaddr_in6.sin6_port). Use ntohs() for consistency.
Flagged by Sparse.
